I prefer using open-PIPE to backticks because you easier get errors, e.g.

unless (open (CMD, "$anycommand |")){
  die "Error in executing $anycommand: $!\n";
}
else {
  my @result = <CMD>;
  close (CMD);
}

I always try to use perl internal functions if possible. Only if there are very important reasons, I use operating system commands, e.g. $anycommand = "dir /b /s *.doc"; or the like instead of File::Recurse, because it is faster.
